In order to create a user, you have to connect as an existing user.
When you use -W, you tell the createuser command to _always_ prompt
for the (existing) password before allowing you to connect, even if
your configuration does not require password authentication.
So, even with the second command, you're still only using 1 password
when you create the account. I feel that the man page for createuser
explains this pretty well.
